please help! What is the empirical formula for a compound that has 1 mole of nitrogen and 2.5 moles of oxygen?
1 answer:
Answer:
Explanation:
usually, the first step is to calculate the moles but since that is already given in the question we can move onto the next step
<u><em>least molar ratio:</em></u>
N = = 1
O = = 2.5
when the answer is in decimals we will multiply it by an integer in order to make it a whole number (in this case 2)
O = 2.5(2) = 5
in order to balance, we will also multiply the atoms of N by the same integer
N = 1(2) = 2
thus, the empirical formula is

Work Shown:
We have the following variables
- Q = 714 joules = heat required
- m = 52 grams = mass
- c = specific heat = unknown
= 82-30.5 = 51.5 = change in temperature
note: the symbol is the uppercase Greek letter delta. It represents the difference or change in a value.
Apply those values into the formula below. Solve for c.
The specific heat of the unknown metal is roughly
